No. 399,387. Patented Mar. 12. 1889 'llll e, gene i s To all whom it may chit? j} Be it-known that I, ED ABD I; OLAN, a citizen of the United States, residing atPhiladelphia, in. the countyof Philadelphia and 5 State of Pennsylvania, have invented certain new anduseful Improvements in Hand Soldering-Irons;and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereomwhieh form a part of this specification. g 'This invention relates'to certain newand useful improvements in hand soldering-irons; and it has for its object to provide a soldering-iron of thisclass which shall be provided with an absorbent core terminating in a point or other suitable form of soldering-surface.

A serious objection to the use of the ordinary copper soldering-irons heretofore used has been raised from the fact that in the heating of the iron great'care has been necessitat-ed, as when heated to a high degree the tin is burned off from the contact-point, thus rendering retinuing necessary. Ithas also been found that when the c pper soldering-surface is used it rapidly wears away, and in consequence it is found to be necessary to frequently reforg'e or otherwise sharpen the tool, which operation consumes a great amountof time and results in a lossof copper. I have distzovered thatall of these objections can be obviated and a much' more durable andserviceable soldering-iron can be produced by providing the soldering-iron of the ordinary and well-known form of construction with a central longitudinal opening, and by filling such opening with a? mass of granulated metal, iron filings, sheet-tin, or other metal rolled into a compact bunch, or by providing a filling composed of a series of wires gathered into a compact mass, and while any of these substances may be employed, and my inven: tion contemplates their use, still I prefer the use of the wires, as I have found that the best results follow such use, and in the accompanying drawings I have illustrated this proferable form ofconstruction only, as it is at Aii'riillrlsts 00F :55. .THE QIIREn IfQCA T3101; iorrning part of Letters Paton N Application filed October 13, 1888- "Serial H0. 238

case granulated metal or iron filings is used, it will be necessary toprovide a wire screen or other suitable guard at the end of the iron, 5 5

which will serve to l-etain the core or filling in place.

The invention is clearly illustrated in the accompanying'drawings, which .form a part, of this specification, and in which, in. Figure 1, I have shown a longitudinal central section through a soldering-iron constructed in accordance with my invention. Fig. 2' is a persection. Fig. 3 is a perspectivevi'w'of a modificatiomthe same being shown partly in section.

. Reference now being had to thefdetails of the drawings by letter, Arepresentsthe handle, B the'shaft, and C the head, of a soldering-iron. The head Got the iron is provided with a central longitudinal opening, D, extending from a point near the base of the head to the extreme outer end of the same. E represents a mass of pa'rallelwires, which are preferably, though notnecessarily, of platinum. These wires are gathered into a compact mass, and when in place within the open ing D they serve to completely fill the opening, and the end ot: the mass of wires is extended beyond the outer end of the iron, and is sharpened or otherwise suitably fashioned into a soldering-s11 rface.

From the foregoing description the operation of the device will be readily understood.

In Fig. 3 of the drawings l have shown a moditied form of iron,in which in lieu of the wires. I have shown the chamber within the iron filled with iron filings. In order to retain the filings within the chamber, 1 provide a screen, G, of wire. This screen maybe secured in place in any suitable manner; but in the present inst ant-e lhave shown the outer end of the chamher as contracted or ol less diameter than the body of the chamber, and the screen, Whichls' in place by the bearing of its outer face at its enlargedlnnerend against the inner faces of theeont raetedwnlls ol' theonlh-l of thccham- Al'ler heating the iron the pointis ino'nee taken up by capillary attraction and fills the p pfllaiyspaees" between-s the wiresh The iron 1s"' then"in readiness for use and upon applying the iron to a surface to be anyy'knqwnz form'- ofghajnd sol'deri n g-i ron I soldered a free and uniform flow of solder is at all times assured. i
